Reversing Circuits
This is accomplished with two 3PDT relays and three momentary
operated pushbutton switches (two with normally open contacts and
one with normally closed contacts). L1 and L2 supply power to the
relay holding circuitry. Normally, if the FORWARD, STOP and
REVERSE pushbuttons are to be located remotely from the control,
low voltage relay coils are used. In operation, power is applied to
the SL10U control and the appropriate voltage to L1 and L2. When
PB1 is actuated, the motor will run forward. When PB2 is actuated,
the motor will stop. When PB3 is actuated, the motor will run in
reverse. When the motor is running, a change in direction is not
possible without actuating PB2 (STOP) first. See Figure 14 on page
28.
